Design of Proposed Hybrid Solar Windmill
Abstract
Energy is the ability of doing work. Renewable energy is clean and environment friendly alternative for generation of power. Here a 10W capacity multicrystalline solar panel has been tested and current-voltage and Power-voltage characteristics has been studied at GCET College, Vallabh Vidyanagar, Gujarat, India. The panel was installed due south at the latitude angle 23?of the location. The open circuit voltage was 19.8V and the short circuit current was 0.22A with the insolation in the range of 239 W/m2 to 608W/m2. Insolation was measured with Pyranometer. The testing was done in the month of August 2020. The efficiency of the solar panel was 12.5%. It is proposed that if a small size wind mill can be connected with the solar panel and the power generated by the solar penal and the wind mill can be stored in the battery. The maximum open circuit voltage and maximum short circuit current of the windmill with three blades was 12V and 0.20A respectively. During night time when solar radiation are not available, power can be generated with the windmill. In rainy season when the sky is cloudy and wind velocity is sufficient the power can be generated by the windmill and solar panel both simultaneously. This power can be utilized in the agriculture sector for water pumping and the additional power can be stored and utilized for domestic application. We have tested the performance of the solar pump with rechargeable cells of 3V. It was observed that 0.1L water can be pumped with it in 21second. It could lift water up to 0.30m so if the pump runs for 1day approximately 414L water can be pumped. By scaling up the hybrid model the irrigation and water pumping is possible for small farms. This type of pump can also be used to remove water from house in heavy rains. As it is risky to operate ac pumps due to high risk of electric shock hazards. This proposed hybrid solar wind mill can be proved as a boon to farmers which can provide power for various application in the agriculture sector.
